>>37234867I remember some proposing that N literally is his clone, what with all the Genesect stuff and his naming indicating his number.
It kind of makes sense given Ghetsis is most likely related to the Heroes and that all this was originally an attempt at reclaiming his birth right.
There's also the Zoroark theory, which could explain why they look so similar. That Ghetsis was the first person N met, thus imitating him.
